BURNlSHlNG-TOOL.

SPECIFICATION forming part of Letters Patent No. 628,422, dated July 4,1899.

Application filed March 3, 1896, Renewed October 14, 1898. Serial No.693,561. (No model.)

To all whom it ntay concern.-

Be it known that I, AMBROSE S. VOSE, a citi zen of the United States,and a resident of Boston, in the county of Suffolk and State ofMassachusetts, have invented an Improvement in Burnishing-Tools, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like letters and figures on the drawingsrepresenting like parts.

This invention relates to a tool or instrument of that class employed inburnishing the edges of the soles of boots and shoes, and substantiallysuch as shown and described in United States Patent No. 536,671, grantedto me April 2, 1895; and this present invention has for its object tosimplify, cheapen, and improve tools of the class referred to.

In accordance with this invention the burnishing-tool is composed of twocooperating members, one of which is adjustable bodily with relation tothe other in a manner as will be described, whereby the movable membermay be adjusted into a position or plane parallel to the other member toenable the tool to be used on soles of varying thickness and whereby themovable member may be adjusted into a position or plane inclined withrelation to the other member, so that the active face of the movablemember may be placed in different angular positions with relation to theactive surface of the other member, as will be hereinafter described.These and other features of this invention will be pointed out in theclaims at the end of this specification.

Figure 1 is a front elevation of an edge-burnishing tool embodying thisinvention with the movable member adjusted for use on thin soles; Fig.2, a front elevation of the tool shown in Fig. 1 with the movable memberadjusted into a plane parallel with the stationary member and inposition for use with thick soles; Fig. 3, a side elevation of the toolshown in Fig. 1, looking toward the left;

and Fig. 4:, a section on the line 4 4, Fig. 3, to show the adjustingand clamping screws.

The edge-burnishing tool herein shown as embodying this inventioncomprises a stationary member a and a movable member ct, the saidstationary member being adapted to be secured to a suitable stem, shank,or rod, (not herein shown,) which may be extended into a hollowextension a of the stationary member. The stationary member a isprovided with the edge working face or bed a and with the inclined facea at one side or edge thereof, which is adapted to follow the creasebetween the sole and the upper part of the boot or shoe, and the saidbed or working face a at its opposite side or edge is left smooth andhas cooperating with itthe inclined active face of the movable member aof the tool, which active face is preferably terraced or composed of alower or bottom inclined part 2 and an upper inclined part 3. The lowerinclined part 2 preferably projects beyond the inner side 5 of themovable member a, so that in the normal position of the movable memberthe inclined face 2 overlaps the unflanged edge or side of thestationary member, as clearly shown in Figs. 1 and i. The movable membera is secured to the member a by a binding or clamping screw 1), whichextends through a suitable hole in the member a and into a threadedsocket b in the side of the stationary member, and the said movablemember is adapted to be adj usted or moved with relation to thestationary member by means of adj usting-screws b b adapted to enterthreaded sockets b b on opposite sides of the socket bvand preferably inline therewith. The adj usting-screws b b are provided at their outerends with stems or extensions ?9" b of smaller diameter than the screws19 b and the movable member a is provided with suitable holes I) 17 forthe reception of the outer ends of the screws 19 b and with small holesor openings I) 12 for the reception of the stems b b", which latterholes or openings extend through the member a and form with the holes Z2Z2 shoulders I3 19 against which abut the ends of the screws b o Thelower portion of the stationary member is preferably made wider than theupper portion, so as to formashoulder 0, upon which the bottom of themovable member a may rest to supportfthe same and relieve the screwsfrom strain when the tool is in operation.

From the above description it will be seen that the member a may bemoved or adjusted her a is parallel to the member a.

with relation to the stationary member a by first turning the clampingscrew so as to loosen the member a from the mem ber a and then turningthe adjusting-screws 11 b, so as to partially withdraw them from theirthreaded sockets b N, and it will be seen that if the adjusting-screwsare moved to the same extent or amount the ends of the screws actingagainst the shoulders Z1 U will carry the member a away from the membera into a plane parallel with the member a, after which theclamping-screw b is turned to force the shoulders Z1 Z9 against the endsof the screws 79 b and thereby firmly secure the member a'into itsadjusted position. Furthermore, it will be seen that if either ad j ustirig-screw is moved more than the other adj Listingscrew the movablemember a will be brought into a plane inclined with relation to thestationary member and that the inclination of vthe member a from eitherside of the vertical depends upon which adjusting-screw is moved thefarthest. For instance, if the adjusting-screw b is moved out of itssocket farther than the adj Listing-screw b the lower end of the movablemember will be carried farther away from the stationary member a thanthe upper portion of the member ct, and consequently the pitch or angleof the inclined active surface of the member a will be more acute to thebed a than when the mem- So, also,

if the adj usting-screw b is moved out of its socket farther than thescrew 19 the upper end of the member a will be adjusted farther from themember a than the lower end of the member a, and. therefore the pitch orangle of the inclined active face of the member a" will be less acute tothe bed a These variable adjustments are desirable in an edgeburnishingtool, as it enables the tool to work more efficiently by enabling theoperator to vadjust the tool to soles of varying thickness and bevels onthe outer side of the same.

I claim 1. In an edge-burnishing tool, the combination of the followinginstrumentalities, viz: a stationary member, a movable membercooperating therewith and adjustable into positions parallel andinclined with relation to the stationary member, and means to effectsaid adjustments, substantially as described.

2. In an edge-burnishingtool, the combination of the followinginstrumentalities, viz: a stationary member, a movable membercooperating therewith, a clamping-screw, and adjusting-screws located onopposite sides of the clamping-screw, substantially as described. v

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
